.22 Filtering

[Anabolic Chemist]

Curious if anyone has ever re-filtered their oils from a trusted source with a .22um syringe filter?

If your sourcing high quality products you trust do you think it’s beneficial to extract the oil from the UGL vial into a large syringe, put a .22 filter on that syringe, and the reinject it into a fresh vial just to be extra sure?

Since high quality UGLs already do this are you just introducing more potential for contamination by doing it again yourself without a full sterile set up like a vent etc, or is it a low risk good extra precautionary measure?

Also has anyone ever tested their products for continuation with blood agar plates?

Thread 'Filtering finished oils'

Jan 5, 2025

I see a lot of great posting lately on filtering finished oils. Decided to make a thread to hopefully consolidate all the great info in one spot.

My knowledge is somewhat amateur on this topic, but what I know so far is that for the average user buying 10ml UGL finished oils a PTFE 0.22 13mm Is likely the best choice.

If you have good info on filter types, brands, techniques, etc. I want to know!

It's such an easy and cheap thing to do that it's just lazy and reckless not to filter your non-pharma products.

Do you filter every single pin or just transfer to sterile 10 ml vial?

God no. You filter entire vials at a time. I believe 1 PTFE .22 um filter is good for 10 vials.

Edit: That's in 1 sitting. If you don't have 10 vials to filter, discard the filter afterwards regardless. Do not save for later.

Bro I was filtering 234iu of gh reconstituted .5mls of Bac water per 39iu vial with a 3cc shit spewed all over my face after pushing like 2 ccs through I guess i was pushing to hard. I guess I shouldn't have put a needle on the end and took the stopper off and just pushed the solution into the vial. I even had a needle through the stopper to vent it and I was going pretty slow

Are the filters sterile? You can def get them sterilized and not. The sterile ones are always individually wrapped/sealed FWIW.
